Abstract

In order to estimate the quasi-static pressure of TNT when it explodes in closed space, the calculation model of the quasi-static pressure is derived basing on the theoretical analysis. Moreover, a series of TNT's internal explosion tests are performed, these tests take the explosion vessel and explosion chamber as the closed container. The results show that the quasi-static pressure increases accompanied by multiple reflections of shockwave and the pressure reaches to the maximum when the reflection is over. The ratio of charge quality and volume is the main factor influenting quasi-static pressure. The peak and increasing rate of quasi-static pressure will increase with the growth of the ratio of charge quality and volume. According to the experimental data of TNT's internal explosion, the empirical formula of the peak for the quasi-static pressure is fitted, The formula can be used to calculate of quasi-static pressure's peak value and assess the lethality of internal explosion.
